Thanks Eric
I'd heard that version of events before - but a bit further and suggested that when the pilot dipped the nose the engines cut out, so they had to dive it to try to get them going again - how true who knows spin

However good to hear what may have been the horses mouth smile

I think an interesting thought here is that in 2016 can the Chinese just copy a US stealth fighter and sort of looks the same, but does it work?

We know Russia from this sad episode tried the same and it didn't. Supersonic transport in the 70's was really really pushing the boundaries. It's pretty amazing Concorde did so well, it was almost like France and Britains Apollo landings tech wise. So it worked well for so long, but not surprised the Russian one hit turbulence.

So the Chinese stealth fighters. I bet if you put them up against the F22 raptor and all the modern ground to air missiles we might find history repeating.

Looks good for the hawks in China. Build another airfield in the south china seas. Etc etc.

I think you will find, as John Farley said in the programme, there was very little in common between the Tu-144 and Concorde - apart from the common goal of building a supersonic airliner.

If you are ever in Germany near Stuttgart or Heidelberg it's well worth visiting the museum at Sinsheim:

http://sinsheim.technik-museum.de/en/

Here you can see Concorde and the Tu-144 side by side. You can also go on-board each to see the differences.

Thought the wheels and tyres on the TU144 looked tiny compared to Concorde. That museum is a fantasic two days out. Even the family, who I had conned into going, liked it.

...and the fact that they looked identical. If you showed the man in the street, 99 out of a 100 would tell you the top pic was Concorde

Just because the "man in the street" couldn't tell them apart does not mean they were the same - or even similar.

The wing used on Concorde is WAY more sophisticated than the double cranked delta used on the Tu-144. In fact, the Russians knew very little about how Concorde used the ogival wing to generate a vortex at slow speed to aid landing and take of.

The original Tu-144 design was so lacking they had to install small retractable foreplanes just behind the cockpit to try and get some control at slow speeds.

They were very, very different aeroplanes.

Was it true the Russians had a spy in the Concorde design team? Sorry haven't had time to listen to the doc, but have a few pics taken at Sinsheim if interested.

It is thought that they did - but they didn't get any useful information. Indeed, they were fed duff data on occasion just in case.

What that shows is a massively higher wetted surface area for no more internal capacity.

I think they had serious stability problems with the 144 which is why everything seems a lot bigger - wings, tail etc. The 144 also has flaps - which Concorde did not. Again, it seems slow speed handling was a big problem for them.

I was musing on this yesterday, and the question about whether a Chinese copy of a stealth aircraft would be stealthy.

There is an oft quoted phrase "if it looks right, then it is right"; and I think this phrase is only partly correct because it is certainly possibly to build a facsimile copy that "looks right" but is, in fact wrong.

In reality, form needs to follow function; so if you design something from a fundamental engineering background and it looks right, then it probably is right.

If however you copy the form without understanding the fundamental engineering reasons for that form, then there's a reasonable probability it will be wrong, especially with more complex systems.

Some bits on wikipedia highlight Erics points about stability. It had the wing further back and hence the canards to hold the nose up, but still a high landing speed

When you see the two together close up you notice that the Tupolev has many more curves on it (like a bird) compared to the straighter lines and angles on Concorde.

There you go:































It really brings it home how far we've come when you walk up the aisle of Concorde, it's very narrow and cramped.


A few other pics of Sinsheim whilst i'm in the album, it really is a fantastic place to visit>

I think this was a V1 caught in a tree on land which was held by the US in Germany until reasonably recently:



I'm from Leeds, the first thing you see as you walk in:



Made in Leeds. tongue out







This was pulled out of the sea or a bog or something and pieced back together, compared to a car engine they are very strange, the crankshaft is at the top of the engine IIRC, someone here will know more and why....










There is a tank there which broke down or got stuck in mud in action, the guys didn't want the enemy to seize it so blew it bits. It cracked all over like an egg and ended up in the bottom of the bomb crater. Years later it was discovered, they pulled it out and put the bits back together quite cleverly so all the cracks are still open, but it resembles a tank.
If this ^^ is your thing the museum should be on your bucket list, i'll never forget it.

This has got road trip written all over it. And passing within a mile of Spa on the way down too (well, not taking the all France route).

Finds bucket list

Fantastic, thanks for all of those. Definitely added to the list of must visits!

Funny seeing a Zakspeed F1 car in West (East) colours sneaking into the background of a shot too.
